What is Codex for mobile?

Codex for mobile is a new feature inside the ChatGPT mobile app. It lets developers use the powerful AI coding assistant Codex from their phones. This tool is designed to help people who build software work on long tasks without being stuck at their computer. With over 4 million users using Codex every week, staying connected to active work sessions is now a key part of staying productive. The main goal is to prevent wasted time by allowing users to manage their coding projects from anywhere.

Benefits

The biggest advantage of Codex for mobile is the ability to stay in the middle of a coding session. When you connect your phone to a machine where Codex is running, the app loads the live state of your work. This means you can continue exactly where you left off whether you are on a laptop, a Mac mini, or a remote server. You can review the changes made by the AI, approve or change commands, and see real-time updates like screenshots and terminal output. Your files and security settings stay on your main computer, while your phone receives the updates through a secure connection. This setup keeps your trusted machines safe from the public internet while ensuring your work context is synced wherever you are.

Use Cases

This tool is perfect for several situations where quick decisions are needed. You can investigate bugs while waiting for coffee by asking Codex to check files and run tests. If the AI suggests multiple ways to fix a problem, you can review the options on your phone and choose the best path before you get back to your desk. It is also useful for preparing for meetings. After a conversation, you can ask Codex to summarize updates from emails and chats to create a briefing for your call. You can refresh this summary as new information arrives. Another common use case is capturing new ideas during breaks. You can send these ideas to Codex to start shaping tasks immediately, ensuring you do not lose momentum when you return to your workspace.

Pricing

Codex in the ChatGPT mobile app is currently rolling out in preview on both iOS and Android. It is available for all plans including Free and Go. Remote SSH and Hooks features are also available on all plans. Programmatic access tokens are available for Enterprise and Business plans. HIPAA-compliant use is supported only for eligible ChatGPT Enterprise workspaces when used in local environments.

Vibes

Users are excited about the ability to collaborate on long-running tasks from anywhere. The feature is seen as a significant step in enabling developers to maintain productivity without unnecessary rework. The mobile experience is described as fully featured, allowing users to manage active threads, approvals, plugins, and project context from their phones. The secure relay layer ensures that trusted machines remain reachable across devices without exposing them directly to the internet. This infrastructure gives users confidence that their active session state and context are synced wherever they are signed in with ChatGPT.

Additional Information

OpenAI is releasing several updates to support automation and management at scale. Scoped credentials are issued directly from ChatGPT workspace settings for CI pipelines and internal automations. Security and compliance features are generally available to scan prompts for secrets and run validators. HIPAA-compliant use of Codex is available for ChatGPT Enterprise workspaces, enabling healthcare organizations to support patient care and operational workflows with greater speed and confidence. The desktop app automatically detects hosts from your SSH configuration, allowing you to create projects and run threads inside remote machines just like you would locally.
